Pin 1: VDD (Supply voltage) Pin 2: GND (Ground) Pin 3: RESET (Reset output) Pin 4: SENSE (Voltage detection input) Pin 5: NC (No connection)

Functional Features

1. Voltage Detection: The S-80831CNMC-B8QT2U can accurately detect voltage levels within the specified range.
2. Reset Function: When the detected voltage falls below a certain threshold, the RESET pin outputs a low signal, indicating the need for a system reset.
3. Built-in Delay Circuit: The product incorporates a delay circuit to ensure stable operation and prevent false resets.

Advantages and Disadvantages

Advantages

• Wide voltage detection range allows for versatile applications.
• Low supply current minimizes power consumption.
• High accuracy ensures reliable voltage detection.
• Small package size enables space-saving integration.

Disadvantages

• Limited to voltage detection and reset functions, may not suit all application requirements.
• No adjustable voltage threshold, limiting customization options.

Working Principles

The S-80831CNMC-B8QT2U operates based on a voltage divider network connected to the SENSE pin. When the voltage at the SENSE pin drops below a certain threshold, the internal comparator triggers the RESET output, indicating the need for a system reset. The built-in delay circuit ensures stability by preventing false resets caused by temporary voltage fluctuations.

Detailed Application Field Plans

The S-80831CNMC-B8QT2U finds applications in various electronic devices where accurate voltage detection and reset functionality are required. Some potential application fields include:

1. Battery-Powered Devices: Ensuring proper shutdown or hibernation when battery voltage is low.
2. Microcontrollers: Providing a reset signal to restart the system in case of power supply issues.
3. Industrial Control Systems: Monitoring voltage levels to prevent damage to sensitive components during power fluctuations.
4. Automotive Electronics: Detecting abnormal voltage conditions and triggering appropriate actions for safety and protection.
